Abstract

The invention relates to an effluent COD treatment procedure by anodic oxidation combining the use of two different types of anode with a suitable apportionment of current. The first type of anode comprises an anode based on diamond doped-synthetic diamond. The second type of anode comprises an anode with high oxygen overvoltage containing tin and antimony oxides.
